Clarify the Role of Insulated Connectors

What happens here

The apprentice asks if the insulation on 'bugs' (insulated electrical connectors) matters. The master electrician clarifies that while insulated connectors are certainly beneficial and provide an extra layer of protection, they are not the primary means of preventing electrocution. The main safety measure is to avoid creating a circuit through one's body. He implies that even with insulated bugs, improper handling, such as allowing a live part to contact a neutral wire, could lead to a dangerous situation (e.g., a short circuit or explosion).

Goal: Understand the function and limitations of insulated connectors.
